Thank you for viewing. I'm selling this because I've gained weight and outgrown it. It's a traveler's jacket without lining. It has an inner pocket and no vent. Reference size: I wore it when I was 178cm tall and weighed 70kg. It's a spring/summer item, so it's perfect for this season! It's in good condition, but I've worn it a few times, so please purchase it if you understand that it's USED.
